Abstract

A liquid bipropellant rotating detonation rocket engine was successfully fired at Purdue University. The 6.5 inch diameter engine and operates on a mixture of rocket grade hydrogen peroxide and triglyme. Ignition is accomplished hypergolically, with the addition of a promoter to the fuel. Eight cases of spontaneously initiated, single wave, rotating detonations were observed. Detonation wave speeds were near or exceeding Chapman Jouget calculations. Evidence of condensed phase reactions was also seen, damaging hardware in short order. Both a rotating detonation and a bulk-slapping mode characterized the engine operation.
